I see you are the author of chapter 9. I don't mean to pick on you; the errors in chapter 9 are, I think, representative of the problems found throughout the book. There was a Try It Out in chapter 7 with a Details View control that I simply couldn't get to work -- I went through it a couple of times, and every time I got a runtime error when I tried to update the record.
The point I was trying to make was: I think it would be good if someone at Wrox went through the book to make sure the examples are correct. For example, on page 634 the solution for exercise C in Chapter 9 (NOT A > 0 OR A < 5) reads:
quote:True for integers 5 and below. Integers 6 and above will evaluate to False.
5 < 5 == True...? :)
